Type species. Cerocoma schreberi Fabricius, 1781: 331 , by original designation.

Subgenus diagnosis. Body length: 12–14 mm. Male frontal calli close to each other in the middle of frons; laterally distinctly depressed forming a deep groove just over the eyes, densely punctured ( Fig. 5A ). Male antennae strongly modified: antennomere I dorsally expanded to form a high and large keel with various apical pointed and curved expansions; II small and subcylindrical; III distinctly swollen; IV–VI flattened with evident laminar and pointed expansions; VII subcylindrical, only slightly swollen, and with an apical incision on dorsal side; VIII slen- der, about twice as long as the previous; IX subtriangular and extremely swollen with a thin and curved keel on dorsal side. Male maxillary palpomeres modified: palpomere I simple and slender, about 2.5 times as long as large; II–III wide, flattened and curved; IV about twice as long as large, gradually enlarged from base to apex. Male protibiae with a well developed dorsal keel curved outwards.

Male last visible abdominal sternite in some species with two lateral narrow laminar expansions, variable in length but always visible in dorsal view.
